mruby is an interpreter for the Ruby programming language with the intention of being lightweight and easily embeddable.[4][5] The project is headed by Yukihiro Matsumoto, with over 100 contributors currently working on the project.
mruby 1.0 supports the Ruby 2.1 core API, but none of the standard library. As well as being able to execute most basic Ruby code, mruby also features a bytecode compiler and virtual machine, as well as the ability to be easily embedded and integrated into C or C++ code, in a similar manner to Lua or Tcl.
mruby 2.0.0[6] adds support for several Ruby 2.x methods beyond Ruby 2.1. v2.0.0 also changed to variable length bytecode instructions format.
mruby bytecode can be embedded in C code, and thus, can be compiled into a standalone executable.[7]
mruby also aims[4] to be compliant with the ISO/IEC 30170:2012 standard.[8]
Examplesedit
Calling mruby from Cedit
#include<stdio.h>#include<mruby.h>#include<mruby/compile.h>intmain(void){mrb_state*mrb=mrb_open();charcode[]="5.times { puts 'mruby is awesome!' }";printf("Executing Ruby code with mruby:\n");mrb_load_string(mrb,code);mrb_close(mrb);return0;}
Assuming that the mruby library and headers are installed, the program can be compiled and executed by running the following commands from the terminal:[9]
$ cc example.c -lmruby -lm -o example $ ./example
Precompiled Bytecodeedit
mruby includes a minimalistic virtual machine used to execute mruby bytecode, nicknamed ritevm:
$ mrbc test.rb $ mruby -b test.mrb
The first command compiles Ruby code to mruby bytecode, creating a file called "test.mrb", which can then be executed by appending the "-b" flag to the normal interpreter arguments.[10]
